Abstract

Presents the results of a study of the influence of the presence of an integrated vibration absorbing layer on the physical and vibration damping properties of the experimental samples of composite heat- and soundproofing panels of various compositions and structures. The factors affecting the level of properties of the manufactured experimental samples of composite heat- and soundproofing panels are established. The influence of the composition and structure of experimental samples of composite heat- and soundproofing panel on its characteristics is analyzed.
